Casimir IV Jagiellon vs Oba Ewuare I

Casimir IV's son W

Oba Ewuare I rebuilt Benin City after a civil war, constructing massive earthwork walls and a new palace complex. He reorganized the city's layout with broad streets and fortified gates, establishing the urban plan that persisted for centuries.

Ewuare I created the title of Iyoba (Queen Mother) for his mother, granting her a separate palace outside Benin City. This institutionalized a new political role for royal women in the Benin Kingdom's governance structure.

Ewuare I led military campaigns that expanded Benin's control over the Niger Delta and Yoruba-speaking areas to the west. He conquered over 200 towns and villages, incorporating them into the Benin Empire through tribute systems.

Ewuare I introduced the use of red coral beads as royal regalia, including the coral crown and beaded garments. This established a distinctive visual identity for the Oba and became a symbol of divine kingship in Benin art.
